SHEETMTAL RADIATOR.

T o all it may concern.'

Be it known that I, RALPH E. MosHER, a citizen of theUnited 'States of America, 'residing at vGrrand Rapids, inthe county of Kent and State of Michigan, have invented certain new and usefullmprovements 'in Sheet-Metal Radiators; and I do hereby declare the followin `tobe a full, clear, Tand exact description o` the invention, suchf-as will enable others skilled inthe art to which 'it appertains to' make and use thefsame. j

vMy invention lrelates to improvements 1n metal sections arranged to circulate the heating fluid longitudinally and in succes-` f sion therethrough, supporting rings within said sections, between which rings the sheet metal is securely yclamped to form tight joints between the sections,l binding bolts extending through the series, means for connecting pipes for circulating the heating fluid, and in various features of construction and arrangement, asv will more fully appear by reference to the accompanying drawings in which:

Figure 1 is an end elevation of a -radiator embodying my invention; Fig. 2 a4 side elevation of the same Fig.3 anenlarged 'vertical section of a portion'of the same on the line 3`3 of Fig. l; Fig. 4' the same of a transverse section on the line 4-4 of Fig. 2;

Fig. 5 a plan view of one of the sections .of the radiator showing a horizontal lsection on the line '5-.5 of Fig. 2; Fig. 6 a horizon-l tal sectional view of the same. on the line 6 6 of Fig. 2; Fig. 7 a detail of one of the supporting rings, and, Fig. 8 the. same of the opposm supporting ring. l Like num ers refer to l'ke parts in all of the figures. e 1 represents aV series of hollow sheet metal radiator sections of two corresponding portions having their edges securely 'connected to each other all around the margins; 2 a pipe for admittin the heating fluid; .8 a collar l' for the same aving a corresponding face to that of one ofthe supporting rings 9, and

adapted to 'co-act therewith l 'an outlet pipe for the heating fluid;,5 an elbow for said pipehaving a face adapted to co-act with oneof the supporting rings9; Glegs for the radiator; 6a a connecting member for one pair of the legs having a face adapted to c0- vactl with one of the supporting rings `9. Each section is provided with an outlet opening 12 at its respective ends, one opening upward and the other downward, and surrounding each-'opening and also directly opposite thereto is a raised circular portion 7 whereby the sections are spaced apart when placed one above the other, In each raised portion 7 is an annular concavo-conveX portion at each end of the section, one of thesepo'rtions is depressed, and the opposite one raised to fit within the same.l These annular intermeshing portions thus serve to.

aline the sections and insure a tight joint therebetween. To support these raised portions 7 and firmly press the same in contact Iwith each other to form a tight joint, supporting rings 9 each havin a central, openang therethrough correspon ing Vto the openings 12 are provided and arranged in pairs,

one of each pair having a-raised annularA `and through the entire series; of sections and also through'the collar andfelbow at, the respective u per and under sides of the series, whereby t e whole are securely held in place, and the joints therebetween made tight.

To insure tight joints, it isnot vnecessary to machine -the'rings Where the engage the -sheet metal, but the latteris ormed when stamped with less elevation and depression of the concave-convex annular parts at the joints than the' rings and when clam ed between the rings the parts are forme thereby to closely t by beingfurther formed up between the To permit circulation of heating fluid, the adjacent sides of these supporting rings are cut away'as at 10 form-v ing o enin s therebetween. It will thus be seen t at w en assembled each alternate connection between the various sections is intercepted by the closures 13 and in alternate relation at opposite ends of the sections, whereb the fluid circulation is longitudinally a tornate and in opposite directions inv alternate series through the various radiat ing members, thus securing complete and. satisfactory circulation of Huid whether steam, hot water, or other fluid is used. It

will also be noted that veryl little machiningV is required to make the joints of this device connected to -form thev respective members and are securely held in place by the intermeshing ,tongue and groove formation. When the device is assembled, the' sheet metal is securely clamped and held between these supporting rings and easily packed if occasion requires, but the tongue groove formation around the openingsis considered .suilicient to make tight joints without packing.

What I claim is l Y 1. A radiator comprising sheet metal sections having raised portions near each end to s ace the sections apart, said portions also having concavo-convex circular portions adapted to intermesh with like portions in the adjacent sections, supporting rings in the sections having like concavo-convex portions engaging the like portions of the sections, and clamping bolts extending through the sections and rings.

. 2. A radiator comprisin sheet metal sections having raised circu ar portions near each endand oppositely arranged openings at its respective ends, said raised portions also having concavo-convex annular pori tions adapted to intermesh with like poi'- tions of the adjacent sections, supporting rings `within the section and having lateral openings, and corresponding concavo-con vex portions engaging the concave and convex portions of the sections, and clamping bolts extending through the concavo-convex portions of the sectionsand rings.

3. A radiator comprisin a sheet metal section having a circular raised portion provided with a central opening, circular concavo-conveii` ortions surrounding the said o ening, a co lar havin an opening opposite. t e opening to the ra iator and a circular portion adapted to intermesh with, the' said circular portions to space the sections apart,-

said circular portions also having'intei'mesh.- ing concavoconvex portions, supporting 'rings havingconcave and convex annular portions adaptedto it within said section and support the raised portions thereof, said ringsalso having lateral openings for circulation of i'iuid, acollar having a face adapted to intermeshwith the concavo-convex portion 4of one of said members, an elbow having a face adapted to intermesh with the concavo-convex portion of the opposite member, and bolts extending through the concave and convex portions of'said members, supporting rings, collar, and elbow to clamp the whole together.

5. A -radiator comprising horizont-ally disposed superposed sheet metal members having raised annular portions to space the sections apart and also having openings in each member .at opposite ends and opposite sides ofv the same, means for connecting pipes to the first 'and last section of the series, consisting of a collar above the said members and an elbow below said members, legs on said elbow to support the radiator,

lsupporting rings within theraised portions of said members and having lateral open'- ings for the` circulation of fluid therethrough, and bolts extending through the series of sections, the supporting rings and the pipe connecting means.

` 6. A radiator, cginprising a )series of superposed raised annular'portions to space the same apart, supporting rings in said sections within said portions, a lcollar above the series of rings and raised portions, an elbow below the same, legs integral with the elbow,

and bolts extending through the rings, the collar, and the elbow kat each side of the vertical central openings therein.

QIn testimony whereof I afiix my signature in presence of two witnesses.
